jersey restful代码实例(多种参数类型)

Jersey RESTful WebService框架是一个开源的、产品级别的JAVA框架，支持JAX-RS API并且是一个JAX-RS(JSR 311和 JSR 339)的参考实现

Jersey不仅仅是一个JAX-RS的参考实现，Jersey提供自己的API，其API继承自JAX-RS，提供更多的特性和功能以进一步简化RESTful service和客户端的开发

下面简单介绍一下其客户端、服务端的实现逻辑

客户端Test.java

package com.ardo.client;import javax.ws.rs.core.MediaType;import javax.ws.rs.core.MultivaluedMap;import org.codehaus.jettison.json.JSONException;import org.codehaus.jettison.json.JSONObject;import com.ardo.bean.Info;import com.ardo.bean.Student;import com.sun.jersey.api.client.Client;import com.sun.jersey.api.client.WebResource;import com.sun.jersey.api.client.config.ClientConfig;import com.sun.jersey.api.client.config.DefaultClientConfig;import com.sun.jersey.api.json.JSONConfiguration;public class Test {private Client client ;/** * 初始化jersey客户端 */public void init(){if(client==null){ClientConfig config = new DefaultClientConfig();config.getFeatures().put(JSONConfiguration.FEATURE_POJO_MAPPING, true);client = Client.create(config);client.setConnectTimeout(3000);}}public Info get(String url, String path, MultivaluedMap<String, String> queryParams){try {return queryParams == null?client.resource(url).path(path).type(MediaType.APPLICATION_JSON).get(Info.class):client.resource(url).queryParams(queryParams).path(path).type(MediaType.APPLICATION_JSON).get(Info.class);} catch (Exception e) {e.printStackTrace();}return null;}public String getString(String url, String path, MultivaluedMap<String, String> queryParams){try {return queryParams == null?client.resource(url).path(path).type(MediaType.APPLICATION_JSON).get(String.class):client.resource(url).queryParams(queryParams).path(path).type(MediaType.APPLICATION_JSON).get(String.class);} catch (Exception e) {e.printStackTrace();}return null;}/** * 客户端请求【get方式-返回实体对象|字符串】 * @param args */public static void main(String[] args) {Test test = new Test();test.init();//Info info = test.get("http://localhost:8899/", "jersey/services/hello/get/Tom", null);//System.out.println("请求返回："+info.getCode()+" "+info.getName());String info = test.getString("http://localhost:8899/", "jersey/services/hello/get/Tom", null);System.out.println("请求返回："+info);}/** * 客户端请求【post方式】 * @param argc * @throws JSONException */public static void main4(String[] argc) throws JSONException {          Client c = Client.create();          WebResource r=c.resource("http://localhost:8899/jersey/services/hello/getpost");          JSONObject obj = new JSONObject();          obj.put("name", "张晓梅2331");          obj.put("school", "华北大学2342");          JSONObject response = r.type(MediaType.APPLICATION_JSON_TYPE).post(JSONObject.class, obj);             System.out.println(response.toString());             } }

服务端 ArdoService.java

示例代码中展示了多种方式：get、post、文本、xml、json、多路径参数、多动态参数匹配等
